Hi Daniel,

I have used 6 vectors just for a trial run. This time I have used all the
260 vectors for the calculation ( Even though the protein have 293
residues, I have consider 260 vectors for calculation since I am
calculating the order parameters for CB-CG vector). I used 30,000 frames
for the calculation. Even though the calculation went successfully with
outputting order parameters for all 260 vectors, after the calculation I
got a message in the terminal that says " FYI: NEVEC > NELEM: Number of
calculated evecs were reduced to 260 ". What does this message means?


Thanks in advance

Regards
Anu
